# Seven Days of Antibiotics Matched Four Weeks After Orthopedic Infection Surgery

*The 500-patient SOLARIO trial found short courses noninferior, with dramatically fewer side effects*

## In brief

- The 500-patient SOLARIO trial found antibiotic courses of 7 days or less noninferior to 4-plus weeks after orthopedic infection surgery
- Treatment failure was 11.1% with the short course versus 14.1% with the long course; side effects were 17.2% versus 45.2%
- Trump has reportedly ordered Vought to draft an executive order putting political appointees over NIH grant review of $48B in research
- Pennsylvania asked the CDC to publicly recognize its four measles deaths as a condition of accepting an Epi-Aid; the state has 792 cases
- Trump proposed splitting childhood vaccine doses into five shots at 20% strength; experts say that would render vaccines ineffective

When an orthopedic implant or bone gets infected, the standard fix is surgery plus a long grind of antibiotics — typically at least four weeks of systemic therapy, with all the nausea, organ stress and hospital time that entails. A trial called SOLARIO, reported last week in the New England Journal of Medicine and covered by CIDRAP, asked whether that grind could be cut to seven days or less, provided the patient also got local antibiotics delivered by a device implanted at the infection site during surgery.

The trial, run at 25 sites across the United Kingdom, Austria, Germany, Portugal and Spain, randomized 500 patients who had undergone surgery for a confirmed orthopedic infection to either a short course (seven days or less) or a long course (four weeks or more). “Orthopedic infection is usually managed with surgery and prolonged systemic antibiotic therapy,” the Oxford University Hospitals–led team wrote. “Whether local antibiotics delivered by a product implanted at the infection site during surgery can reduce the duration of systemic antibiotic therapy is unclear.”

Now it is less unclear. Definite treatment failure by 12 months occurred in 14.1% of the long-course group and 11.1% of the short-course group — a risk difference of –3.0 percentage points, comfortably inside the prespecified 10-point noninferiority margin, with sensitivity analyses consistent. Notice what those numbers say: the short course wasn’t merely “not worse”; fewer patients failed on it, though the trial was designed to prove noninferiority rather than superiority. The side-effect gap was enormous: 45.2% of long-course patients had potential antibiotic side effects, versus 17.2% of short-course patients, a risk difference of –28.0 percentage points. “The anticipated advantages of short-duration therapy, which include fewer symptoms associated with treatment and shorter durations of hospital stay without an increased risk of death or serious adverse events, were seen in the current trial,” the authors wrote. Four weeks of extra drugs, no detectable benefit, and nearly three times the side effects is a trade that increasingly looks hard to justify.

## A political layer for NIH grants

The White House is seeking greater control over $48 billion in federal research funding, according to reporting from the Washington Post, New York Times and Politico summarized by CIDRAP. President Trump has reportedly told Office of Management and Budget Director Russell Vought to draft an executive order requiring that National Institutes of Health grant applications be reviewed by a board of political appointees. The Times reports the goal is to promote conservative ideology and cultural change by steering scientific research at prestigious universities.

Understand what that would replace. Today, NIH applications pass through a two-step review: study sections of non-federal scientists score the science, and the relevant national advisory council or board weighs in, with final approval resting with the director of the specific institute, such as the National Cancer Institute. The proposed change inserts political appointees into that chain. It is also not Vought’s first attempt: in May, his office floated a rule requiring “senior appointees” chosen by politically appointed agency heads to review NIH proposals, with language stating the change would ensure that “discretionary awards advance the President’s policy priorities” and specifying that funding cannot go to research endorsing “the notion that sex is a chosen or mutable characteristic.”

The academic-freedom pushback has been blunt. “These actions show us an administration determined to take control of our science,” said Stand Up for Science CEO Colette Delawalla, PhD, warning the rule threatens decades of peer-reviewed research. The peer-review system’s entire premise is that funding decisions get made by scientists judging science; the premise of the proposed order is that they get made by appointees judging alignment. Both premises cannot hold at once.

## Measles deaths and split doses

In Pennsylvania, the measles outbreak has reached 792 cases, with 93 new cases in the last week, 150 hospitalizations and four deaths, according to the state’s dashboard. State Health Secretary Dr. Debra L. Bogen sent the CDC a letter formally asking the agency to recognize the four deaths as a condition of receiving its emergency assistance, known as an Epi-Aid. “The CDC’s choice not to publicly recognize the deaths undermines our response,” Bogen wrote, adding that “if CDC is unable to transparently and accurately communicate information about those measles-associated deaths, the Department will respectfully rescind our request for a CDC Epi-Aid.” Gov. Josh Shapiro first mentioned the request late last week.

And in the Oval Office on Friday, Trump said he would propose splitting some childhood vaccine doses into five separate shots at 20% of a single dose: “We’re going to recommend that they do five doses marked one, two, three, four, five and that they be given in six-month intervals, so that a small amount of the vaccine gets pumped into the body.” He did not say which vaccines he meant, but suggested the change would produce a “massive reduction in autism.” Vaccine experts quickly responded that the plan would render vaccines ineffective — as they did earlier this year when he suggested splitting the measles, mumps and rubella shot into separate vaccines. The medical literature on vaccines and autism has not moved; the dosing proposals keep coming anyway.
